Came to post this. A good cat that normally pees in the box that is peeing elsewhere is a sign of a physical problem. DEFINITELY get him checked out. My sister had this problem with one of her cats a couple of years ago, and it turned out he had a urinary blockage that had to be removed. If you let it go for too long, their kidneys can get backed up with toxins and they can die.
